How many sporangia are generally present inside an anther?

4

An anther is a sac-like structure in the stamen of a flowering plant. It contains the microsporangia, which are the sporangia that produce the pollen grains. Each anther has two lobes, and each lobe contains two microsporangia. Therefore, a typical anther has four sporangia.

In some plants, the anther may have only one lobe, or it may have more than two microsporangia per lobe. However, four is the most common number of sporangia in an anther.
